ranged in sliding lit between the transoins 16 16 and short enough for suitable playf'transversely ofthe truck. The u per and lower beams of each face of the bo ster arel preferrlgidly connected by open trusswork,

28 28 indicate the center-bearing arch-bars carrying the center-bearing block 29 and secured to the bolster-beams 24.

It will be seen that the construct1on 'de-v kscribed provides a hollow bolster of skeleton trusswork supported in the truck-frame for vertical and lateral movement relative thereto andrelative to the wheels by which the truck-frame is resiliently supported.

Within the hollow bolster, preferably constructed as described, I mount the motor or motors for drivin the traction wheel or flexible' connection between the motor or motors and the traction wheel or wheels as will accommodate itself to the relative chan es in position between said `Wheel or ls and the bolster without affecting the constant transmission of power from the motor tothe traction wheel or wheels.

, In'practiceiI prefer that both axles of the as that shown, wherein 25 and 26 are i `wheels of the truc and provide for such a I truck should be'driv'en, and to this end I have herein shown in Figs. 1 to 4 an arrangement whereby. ower is transmitted to each axle yfrom an in ependentmotor, both of said. motorsbeing mounted in the truck-bolster, and in Fig. 7 I. have shown an arrangement for driving both axles from .a single motor. Obviously, however, if preferred, .a single.-

motormight be employed to drive `a single IIO )4o lbearings in-a framework, generaiir imin axle of a single traction-wheel under the teachings of my-present application.

Referring now to the showing made-in Figs. 1 to 4, A and A indicate in general motors, preferably mechanical motors, (as distinguished from electrical motors,) and which I refer shall be rapid-combustion engines. 'he motors are herein shown as horizontal four cylinder gas engines, having, respecro tively, ri id crank-boxes .c and a. The two -=engines and Aare preferably arranged at opposite sides of the bolster with their crankboxes a a suitably separated and their cylinders extendin outward toward opposite sides t5 of the truckame. Preferably the engines have their crank-boxes bolted `direct to the lbeaune-23 24 of the bolster, so that they tend to strengthenthe bolster construction. The `engine Ais shownas provided with the main zo 4shaft .32, projecting forwardly beyond the bolster vand carrying at its front end a iiyvwheel 33. The opposite engine A is provided with the shaft 32 and y-wheel 33', arranged in rear of the bolster. The engine 12 5 A is arranged vto drive the front axle 13, and

the engine A the rear axle 13; but the coniections between the respective engines Vand the axles being duplicates I `will describe only the connection of the engine A with its 3c axle 13, it being understood that the opposite engine is in like manner connected with thema e 13', likearts Abeing Aindicated by -like numerals of reference, differentiated yby the exponent prime (7). 34 indicates-a beveled gear secured to or formed'upon vthe face 4of the ily-'wheel 33, and 35 35 indicate bev-v eled pinicns meshing therewith and loosely mounted upon a counter-shaft*section 36* lThe shaft-section 35 is supported in suit bl -fas at 37 and'carried by the bolster. buit .ableclutch mechanism for clutching either -of the pinion's-B to 'the shaft-section 36 is provided, such clutch member being herein 4.5 indicated-at 38. It will be understood that said member 38 is slidable :longitudinally relative to the shaft-section-36, but is fixed :against rotation relative thereto. A flexible and extensible driving connectionis aiorded `5o between the shaft-section 36 and the axle 18, and in the specific embodiment herein shown 39 indicates the gear,.and 40 the-pin'- -ion, of a reduction-gearing, the lgear 39 being affixed to the shaft 13 :and the pinion 40 455 mounted on the counter-'shaft section 41, which bears in the gear-case 42, supported `on shaft 13 and positioned by link 42'., pivotally connected to the bracket 42"', carried 4by the bolster. It will be understood that the simple gearing shown is illustrative merely and that any desired speed-change gearing might be empioyed. Shaft-section 41 is connected by-a universal joint 43 with shaft-section 44, into which telescopically 1 165 interts .the .shaftsection 45, making suc axle. 'having mounted thereon,: as described, :two separate engines, means should 2be provided ition, and suitable connection, hereinsuggested by the broken'links A56 56, gare-extended from said operating-levers vi4-to suitvengineand the shaft to be driven and to permit free play of-the engine with the movable bolster without interferin 'with the ei- 7 5 ciency of the vdrive from t een 'ne to the Where two trucksare emp oyed,'each for operating the clutches which control :the connection of the engines with their :axles simultaneously andin proper-direction. a simple means of voperating fthe clutches-Il have shown' the clutch member3'8 as rovided with a shipperelever 48, connecte by `85 link 49 with the end of -'a diagonally-'disposed-lever 50, the-op osite end=of\whieh=is connected with the ongitudinally-cxtending rod 5,1,connected Vto one side cfa trans verse llever 52, pivotall i secured, las upona .90 shaft 53, to which is a so secured the operating-.lever 54. The opposite -side :of said lever, it =will be understood, yis connected through like connections with the clutch member 38, flike parts being indicate'dby 95 like numerals with the exponent rime The operating-bars 54 54 of the front-,zand rear trucks are preferably connected together by a link 551er simultaneous actua POO able controlling mechanisms at each end of the car, (not herein. speciiicallyshowin) but 'which will readily `occur yto ythose skilled m 1o 5 theart.

While I have herein -describedithe ar connection between the engines' and t cir shafts as being positive in their nature, I del sire Iit 'to be Iunderstood that friction-drive may be employed, if=desirable, fandtherefore I have shown 1n 7 means for'driving-the axle Vfrom the engine through friction-gearing.

-movement of said shaft 36- away from the ily-wheel being accomplished through the agency of suitable sprinl 68, bearing against the lever 64. Itwill e understood that suitable mechanism is. provided at `each vend of the car to enable the operator to control the movement of the shaft 67 and thatlike.
